After seeing Rishbala getting married on tv n seeing how Madhu told him to go away!
He should go home and scream and say I failed! I failed you mum to get you your revenge and then we should have had a flashback of sultan finding fahid and finding his mum n his dad is Mohan Kundra (all the scenes they showinf now should be a flashback from before sultan met madhu in thr woods) and then flashback of how he researched RK ans Madhu and then u knw when Rk sees his eyes in the chawl when they are looking dir madhu Sultan realises his pawn can be madhu to get his mums revenge brainwashed manipulated Madhu to be his friend and hw he is using her to get revenge on RK! So everything would have been better
